We did search on single cell sequencing datasets of influenza vaccination, healthy and treatment of disease for HV6-1 signature matched sequences (PMID:33287869, 32573488, 32866963); however, zero reads matched HV6-1-sequence signature because of low number of IGHV6-1 germline sequences in recovered cells. The gene discussed is IGHV6-1; the disease is influenza.
